Electric vehicle range remains one of the most closely watched metrics among buyers, particularly as manufacturers compete to improve efficiency and reduce charging stops. Official laboratory figures offer one benchmark, but real-world tests often provide a clearer picture of how vehicles perform in everyday conditions.
That is why the latest summer range test organized by NAF has attracted attention across the EV sector. The exercise compared real-world performance against WLTP ratings, the European testing standard that is generally considered more generous than the EPA ratings used in the United States.
BMW iX3 Exceeds Its Official Range Rating
The BMW iX3 recorded a real-world range of 485 miles during the Norwegian test, the highest result among all vehicles evaluated.
What made the performance particularly notable was that the vehicle exceeded its official WLTP-rated range by around seven miles. That represented a positive deviation of 1.5%, making the iX3 one of the few models in the test to outperform its certified figure.
The Lucid Gravity secured second place with a real-world range of 447 miles. Its result was 3.7% lower than its WLTP rating of 465 miles.
Behind the two leaders, the Mercedes-Benz CLA, Mercedes-Benz GLC 400 and Xpeng X9 completed the top five positions in the rankings.
Large Gaps Emerge Between Official and Real-World Results
Beyond the overall standings, the test highlighted significant differences between advertised and measured driving ranges.
According to the data reported by Autoblog, the MG IM6 showed the largest negative deviation. The model delivered 277 miles in real-world driving, falling 11.7% short of its WLTP-rated range. The vehicle is not sold in the United States.
At the other end of the spectrum, the Xpeng X9 produced the strongest positive deviation in the test. The Chinese electric vehicle increased its range from a WLTP rating of 360 miles to 401 miles in real-world conditions, an improvement of 11.4%.
The Toyota bZ4X, marketed in the United States as the Toyota bZ, produced one of the most consistent results. Its official WLTP range and the distance achieved during NAF’s test both stood at 314 miles.
Automakers Continue the Push for Greater Efficiency
The results arrive as manufacturers continue to focus on extending EV range through advances in battery technology, vehicle architecture and efficiency improvements.
Real-world driving range can still vary depending on factors such as driving style and speed. Drivers who accelerate aggressively or spend more time at higher speeds may achieve different results from those recorded during organized tests.
BMW’s latest electric SUV illustrates the industry’s broader direction. In the United States, the automaker lists the iX3 with an estimated range of up to 434 miles. The model is also the first BMW built on the company’s all-electric Neue Klasse platform.
The vehicle uses an 800-volt architecture and can charge from 10% to 80% using DC fast charging in 21 minutes under ideal conditions, according to BMW.
